Are you sure that you are using industrialcraft-2-2.8.111-ex112.jar? I tried to mine nuclear reactor, kinetic generator, MFSU and recycler with an unenchanted diamond pick and it works in that version and in 2.8.118.

What did you do exactly after changing the config file and before mining machines? What other mods are you using (if any)? What's the forge version that you use?
